  • 📁 You can transfer entire folders without archiving.
  • 🔒 There are no file size limits.
Why might FTP not work?

If your PC cannot connect to your phone's FTP server, check:

1. Antivirus/firewall on PC - they can block port 21 (FTP).

2. Network mode On your phone - some apps require a Wi-Fi connection instead of mobile data.

3. IP address - If the phone is connected to a VPN, the local IP will change and the FTP server address will become invalid.

5. Cloud services: when Wi-Fi is unavailable

If the devices are connected to different networks (for example, a PC at work, a phone on home Wi-Fi), the easiest way is to use cloud services: Google Drive, Dropbox, Yandex Disk or iCloudThis method is universal, but has limitations:

  • 🌍 Requires Internet (speed depends on the provider's tariff).
  • 📉 File size limit (for example, in Google Drive — 750 GB/day for free accounts).
  • 🔐 Data is stored on the company's servers (risk of leakage when transmitting confidential information).

📤 How to transfer a file via Google Drive:

  1. On PC: Download the file to Google Drive (drag and drop into browser or via app).
  2. Right-click on the file → “Share” → copy the link.
  3. On your phone, open the link in a browser or app Google Drive and download the file.

⚠️ Attention: When transferring large files (from 1 GB) traffic is consumed via mobile internet. If you have an unlimited plan with a speed limit after a threshold (for example, 10 GB), loading may take hours.

6. Troubleshooting: Why Files Won't Transfer Over Wi-Fi

Even with proper setup, file transfers over Wi-Fi may be interrupted. Here top 5 reasons and ways to eliminate them:

Problem Cause Solution
The devices don't see each other Different Wi-Fi subnets (for example, PCs in 192.168.1.x, phone in 192.168.0.x) Connect both devices to the same network or configure the router to the same subnet
Low transmission speed The router is running on 2.4 GHz or uses channel width 20 MHz Switch to 5 GHz and set the channel width 40/80 MHz in the router settings
Connection break Weak Wi-Fi signal or interference from other networks Move the router closer to the devices or change the Wi-Fi channel in the settings
"Access Denied" error A firewall or antivirus is blocking the connection. Temporarily disable protection or add an exception for the application

🔍 Network diagnostics:

If problems persist, check Wi-Fi connection quality:

  1. On PC: Open Command line and enter: 
    ping 192.168.1.1 -t

    (replace 192.168.1.1 to your router's IP). If packet loss is >5%, the signal is weak.

  2. On your phone: install the app WiFi Analyzer and check the signal level (should be >-60 dBm).

FAQ: Frequently asked questions about transferring files over Wi-Fi

Is it possible to transfer files via Wi-Fi without a router (directly)?

Yes, you need to create one for this access point on one of the devices:

  • On Android: Settings → Hotspot & tethering → Wi-Fi hotspot.
  • On iPhone: Settings → Tethering.
  • On Windows: use the command in Command line: 
    netsh wlan set hostednetwork mode=allow ssid=MyWiFi key=12345678 && netsh wlan start hostednetwork

After connecting the second device to the created network, use any transfer method (FTP, LocalSend, etc.).

What is the most secure method for transmitting confidential data?

According to the level of security, the methods are ranked as follows:

  1. LocalSend (TLS encryption).
  2. FTP with password (set up authentication in the file manager application).
  3. AirDrop (Apple encryption, but closed ecosystem).
  4. Cloud services (data is stored on third-party servers).
  5. Snapdrop (no encryption).

For maximum protection, turn off Network sharing on PC after transfer and use VPN when working with clouds.

Why is Wi-Fi transmission speed lower than cable?

Wi-Fi is always inferior to cable in terms of speed due to:

  • Interference from other networks (especially in apartment buildings).
  • Limitations of the standard: even Wi-Fi 6 (802.11ax) gives the maximum 9.6 Gbps in ideal conditions, but the actual speed is 100–300 Mbps.
  • Overhead costs for encryption (WPA3) and connection management.

To speed things up:

  • Use range 5 GHz.
  • Connect the devices to the router via Wi-Fi 6 (if supported).
  • Disable the function on your router Band Steering (it can force devices to switch to 2.4 GHz).
Is it possible to transfer files between Android and iPhone via Wi-Fi?

Yes, but not all methods are suitable:

  • ✅ LocalSend or Snapdrop — work cross-platform.
  • ✅ FTP server (on Android through ES File Explorer, on iPhone — FileExplorer).
  • ❌ AirDrop And Nearby Sharing — are not compatible.

For iPhone transmission via is also suitable iCloud Drive (upload the file from your PC, download it to Android via browser).

How to transfer files from Linux to phone?

On Linux All methods work except Nearby Sharing (no official support). Best options:

  1. LocalSend: install via Flatpak: 
    flatpak install flathub org.localsend.localsend_app
  2. FTP: use vsftpd or proftpd to create a server on a PC.
  3. SSH: if there is one on the phone Termux, you can copy files via scp: 
    scp file.txt user@192.168.1.100:/sdcard/
